SPIRAL SCREW-DRIVER AND DRILL.

Application filed January 10, 1910.

Specification of Letters Patent.

To all whom t may concern Be it known that I, THOMAS J. Fester, acitizen of the United States, residing in Philadelphia, Pennsylvania,have invented certain Improvements in Spiral Screw-Drivers and Drills,of which the following is a specification.

The main object of this invention is to provide a spiral screw driver ordrill with a long grip section, so that the tool can be gripped at anypoint throughout its length by one hand while it is reciprocated by theother hand.

A further object is to protect the spiral spindle and nut from dust anddirt.

The invention is particularly adapted for the use of car builders andothers where some of the parts are inaccessible with a short screwdriver or drill, and while it is of advantage to hold the tool as nearthe chuck as pos-sible, in some instances it is only practical to holdthe tool a distance away from the chuck.

In the accompanying drawing z-Figure 1, is a side view showing the fulllength of drill not extended; Fig. 2, is a view similar to Fig. l,partly in section drawn on an enlarged scale, with a portion cut out;and Fig. 3, is a sectional view on the line 3 3, Fig. 2.

A is a spindle having a spiral groove a cut therein, adapted to a nut bsecured to the shell B by a cap 7). The inner end of this spindle isreduced and rests in a socket in the end of a ratchet spindle C, whichis secured to the shell B and on this spindle is a ratchet wheel c, withwhich engage the pawls fl, cZ, pivotally mounted in the shell D. Theshell is provided at its upper end with a hand hold D.

e is a shifter having a portion e which projects through a slot j in thecasing F encircling the shell, so that on moving the shifter to thecentral position the chuck A, carried by the spindle A, will bepositively driven first in one direction and then in the other directionas the tool is reciprocated.

When the shifter is moved to the lowest position then the tool willpositively turn to the right and ratchet to the left, and when moved tothe upper position the tool will turn to the left and ratchet to theright. I

lay no claim to this ratchet mechanism, as any suitable ratchetmechanism may be used.

I is a sleeve mounted on the spindle A between the end a ol the chuckand a ring a2 secured to the spindle, so that the sleeve has nolongitudinal movement independent of the spindle, but is free to rotatewithout rotating the spindle. Mounted on this sleeve is a long tube J,in the present instance the tube is threaded and adapted to the threadedperiphery of the'sleeve and the opposite end of the tube is threaded,and adapted to the tube is a sleeve vf through which slides the shell B.By this construction I provide an extended handhold for one hand of theoperator, so that the tool can be held either close to the chuck or at apoint close to the handhold, according to the location of the hole to bedrilled or the screw to be driven. Part of this handhold or tube .I isroughened so that a better grip can be had on the tool, and thisroughened surface may extend the full length ot the sleeve, if desired.Furthermore the tool can be passed into a comparatively small openingand readily operated by grasping the outer' end o'tl the tube J.

The shell protects the spiral spindle from injury and as it is closedboth at top and bottom dirt or dust cannot gain access to the spiralgroove or the nut l). In this type of tool the nut cuts away veryrapidly, owing to dust gaining access to the space between the threadsof the nut and the spindle.

I claim z- The combination in a ratchet tool, of a spiral spindle.v achuck at one end of the spindle, a ratchet spindle in which the otherend of'the spindle is seated, a shell attached to the said ratchetspindle and a nut carried by the said shell through which the spiralspindle extends, a ratchet wheel on the ratchet spindle, a shellinclosing said spindle, pawls mounted on the shell and arranged toengage the ratchet wheel, a casing inclosing the shell and slotted, ashifter for the said pawls extending through the slot, a hand hold atthe outer end of the shell inelosing the ratchet spindle, with anextended tubular hand hold mounted adjacent to the chuck so as to turnfreely on the spiral spindle and on the first mentioned shell whichincloses the spindle, the said hand hold being held so as to movelongtudinaly With the spindle nzune to this specification, in thepresence of whereby an extended hand hold for the spntwo subscribingWitnesses. die is provided7 Which also prevents the entrance of dust tothe spiral groove of the THOMAS J- FEGLEY- 5 spindle and to the nutthrough which it eX- 'Vtnesses:
